Welcome to RD SIPs, a modern, family-run supplier of certified Structural Insulated Panels (SIPs) based in Herefordshire. We support homeowners, self-builders, and trade customers across the UK with SIP panels and complete kits for garden rooms, house extensions, and new build projects, all backed by professional certifications and a practical, helpful approach.

RD SIPs was founded for a simple reason: when our director needed SIPs for his own extension, the big players were not interested in smaller jobs, and the smaller providers were charging a fortune. We built RD SIPs to bridge that gap, giving you the quality and compliance you would expect from a major manufacturer, with the personal service and flexibility of a family-run business.

Whether you are planning a compact garden studio or a full house build, we will guide you through the process with clear advice, honest lead times, and real technical support. Our goal is to make thermally efficient, sustainable building easier, with panels designed to perform, fit properly, and help your project move forward with less stress.
